Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a movable door engaging device for an elevator that closes a gap (running clearance) between a car-side sill and a landing-side sill when an elevator car reaches the landing.
[0002]
[Prior art]
Conventionally, when an elevator car reaches the landing, an engaging member provided on the car side engages with an engaged member provided on the landing side door. Then, the car-side door is opened and closed by the door operator provided in the car, and at the same time, the landing-side door is also opened and closed via the engaging member and the engaged member. Thus, since an engaging member and an engaged member are required between the car side and the landing side, a running clearance (gap) of about 30 mm is provided between the car side threshold and the landing side threshold. It is necessary.
[0003]
[Problems to be solved by the invention]
However, in such a conventional elevator, there is a running clearance of about 30 mm between the car side sill and the landing side sill. When passing over, there was a problem that these wheels would fall into this gap.
[0004]
An object of this invention is to prevent wheels, such as a wheelchair and a trolley | bogie, falling in the clearance gap of a sill and to pinch | interpose.
[0005]
[Means for Solving the Problems]
In order to achieve such an object, in the present invention, the engaged member provided on the landing side door and the engaged member are engaged with each other when the car side door is swingably provided and swings. Engaging member, urging member that urges the engaging member to a position where it can be removed from the engaged member, a guide rail disposed in the vicinity of the engaging member, and slidable on the guide rail A pressing member that can be pressed against the engaging member and a driving unit that slides the pressing member along the guide rail. The driving unit slides the pressing member along the guide rail. Then, the pressing member is configured to engage the engaging member with the engaged member against the urging force of the urging member.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described with reference to the drawings. 1 to 5 are views showing an embodiment of a movable door engaging device for an elevator according to the present invention.
[0007]
As shown in FIG. 1, a hanger 2 is provided on the upper end side of the car-side door 1, and the hanger 2 is slidably supported on a door rail (not shown) via a roller 3. The hanger 2 is provided with a support member 6 having a pin 5, and a car cam (engagement member) 4 having a substantially L-shaped cross section and extending in the vertical direction swings on the pin 5. It is supported freely.
[0008]
As shown in FIG. 2, the car cam 4 is located in a notch 2a formed in the hanger 2, and the car cam 4 can swing through the notch 2a. The urging force of the spring 7 attached to the pin 5 acts on the car cam 4, and the urging force causes the car cam 4 to rotate counterclockwise in FIG. 2. The tip 4a of the car cam 4 is located between a pair of stopper portions 8 and 9 provided on the hanger 2. The stopper portion 8 prevents the clockwise rotation of the car cam 4 at a predetermined position, and the stopper portion 9 is counterclockwise. Is prevented at a predetermined position.
[0009]
Further, an engagement member 10 having a substantially U-shaped cross section is provided on the rear surface side (the upper surface side in FIG. 2) of the car cam 4, and the pressing roller 11 is in contact with the engagement member 10. The pressing roller 11 is provided on the support member 12. When the pressing roller 11 moves to the right in FIG. 2 together with the support member 12, the engagement member 10 is pressed to rotate the car cam 4 against the urging force of the spring 7, and the tip 4a. Is projected from between the stopper portions 8 and 9. Then, the tip 4a of the car cam 4 enters and engages between a pair of engaging rollers 14a and 14b (engaged members) provided on the landing door 13 as shown in FIG. Further, the pressing roller 11 can be engaged with both end portions of the engaging member 10, and when engaged, the car-side door 1 is opened and closed via the engaging member 10.
[0010]
A support member 12 that supports the pressing roller 11 is fixed to a belt 15, and as shown in FIG. 1, the belt 15 is hung on a driven pulley 16 and a drive pulley 17 disposed above the door 1. The drive pulley 17 is rotated by a motor 18. The support member 12 is slidably engaged with a guide rail 19 disposed in the opening / closing direction of the door 1.
[0011]
As shown in FIG. 4, when the pressing roller 11 does not press the engaging member 10, the car cam 4 receives a counterclockwise biasing force by the biasing force of the spring 7, and the tip 4 a is interposed between the stopper portions 8 and 9. It is located and does not protrude from the car side sill 20. Thus, when the front end 4a of the car cam 4 is located between the stopper portions 8 and 9, the car side sill 20 does not protrude. Therefore, the car-side sill 20 can be disposed close to the landing-side sill 21 and the running clearance can be set to about 10 mm, for example.
[0012]
Immediately after the car has landed, the tip 4 a of the car cam 4 is located between the stopper portions 8 and 9 by the urging force of the spring 7, that is, located in the car-side sill 20.
[0013]
Next, when the belt 15 is rotated by driving the motor 18, the pressing roller 11 first presses the engaging member 10, and the car cam 4 rotates together with the engaging member 10 in the clockwise direction in FIG. 3 and rotates by the stopper portion 8. This tip 4 a protrudes from the car side sill 20.
[0014]
Then, as shown in FIG. 5, the tip 4 a of the car cam 4 is positioned and engaged between a pair of engagement rollers 14 a and 14 b (engaged members) provided on the landing-side door 13. Next, the pressing roller 11 engages with the end of the engaging member 10 to open the car-side door 1, and simultaneously opens the landing-side door 13 via the car cam 4 and the engaging rollers 14a and 14b.
[0015]
【The invention's effect】
As described above, according to the present invention, when the pressing member is slid along the guide rail by the driving means, the pressing member engages the engaging member against the engaged member against the urging force. Thus, the car side sill can be arranged close to the landing side sill. As a result, the running clearance can be narrowed, and wheels such as wheelchairs and carts do not fall into the running clearance and get caught.
